Silk Road Author Arrested Due to Bad Operational Security

Details of how the FBI found the administrator of Silk Road, a popular black market e-commerce site.

Despite the elaborate technical underpinnings, however, the complaint portrays Ulbricht as a drug lord who made rookie mistakes. In an October 11, 2011 posting to a Bitcoin Talk forum, for instance, a user called “altoid” advertised he was looking for an “IT pro in the Bitcoin community” to work in a venture-backed startup. The post directed applicants to send responses to “rossulbricht at gmail dot com.” It came about nine months after two previous posts—also made by a user, “altoid,” to shroomery.org and Bitcoin Talk—were among the first to advertise a hidden Tor service that operated as a kind of “anonymous amazon.com.” Both of the earlier posts referenced silkroad420.wordpress.com.

If altoid’s solicitation for a Bitcoin-conversant IT Pro wasn’t enough to make Ulbricht a person of interest in the FBI’s ongoing probe, other digital bread crumbs were sure to arouse agents’ suspicions. The Google+ profile tied to the rossulbricht@gmail.com address included a list of favorite videos originating from mises.org, a website of the “Mises Institute.” The site billed itself as the “world center of the Austrian School of economics” and contained a user profile for one Ross Ulbricht. Several Dread Pirate Roberts postings on Silk Road cited the “Austrian Economic theory” and the works of Mises Institute economists Ludwig von Mises and Murray Rothbard in providing the guiding principles for the illicit drug market.

The clues didn’t stop there. In early March 2012 someone created an account on StackOverflow with the username Ross Ulbricht and the rossulbricht@gmail.com address, the criminal complaint alleged. On March 16 at 8:39 in the morning, the account was used to post a message titled “How can I connect to a Tor hidden service using curl in php?” Less than one minute later, the account was updated to change the user name from Ross Ulbricht to “frosty.” Several weeks later, the account was again updated, this time to replace the Ulbricht gmail address with frosty@frosty.com. In July 2013, a forensic analysis of the hard drives used to run one of the Silk Road servers revealed a PHP script based on curl that contained code that was identical to that included in the Stack Overflow discussion, the complaint alleged.

We already know that it is next to impossible to maintain privacy and anonymity against a well-funded government adversary.

Book Review: Rise of the Warrior Cop

Rise of the Warrior Cop: The Militarization of America’s Police Forces, by Radley Balko, PublicAffairs, 2013, 400 pages.

War as a rhetorical concept is firmly embedded in American culture. Over the past several decades, federal and local law enforcement has been enlisted in a war on crime, a war on drugs and a war on terror. These wars are more than just metaphors designed to rally public support and secure budget appropriations. They change the way we think about what the police do. Wars mean shooting first and asking questions later. Wars require military tactics and weaponry. Wars mean civilian casualties.

Over the decades, the war metaphor has resulted in drastic changes in the way the police operate. At both federal and state levels, the formerly hard line between police and military has blurred. Police are increasingly using military weaponry, employing military tactics and framing their mission using military terminology. Right now, there is a Third Amendment case—that’s the one about quartering soldiers in private homes without consent—making its way through the courts. It involves someone who refused to allow the police to occupy his home in order to gain a “tactical advantage” against the house next-door. The police returned later, broke down his door, forced him to the floor and then arrested him for obstructing an officer. They also shot his dog with pepperball rounds. It’s hard to argue with the premise of this case; police officers are acting so much like soldiers that it can be hard to tell the difference.

In Rise of the Warrior Cop, Radley Balko chronicles the steady militarization of the police in the U.S. A detailed history of a dangerous trend, Mr. Balko’s book tracks police militarization over the past 50 years, a period that not coincidentally corresponds with the rise of SWAT teams. First established in response to the armed riots of the late 1960s, they were originally exclusive to big cities and deployed only against heavily armed and dangerous criminals. Today SWAT teams are nothing special. They’ve multiplied like mushrooms. Every city has a SWAT team; 80% of towns between 25,000 and 50,000 people do as well. These teams are busy; in 2005 there were between 50,000 and 60,000 SWAT raids in the U.S. The tactics are pretty much what you would expect—breaking down doors, rushing in with military weaponry, tear gas—but the targets aren’t. SWAT teams are routinely deployed against illegal poker games, businesses suspected of employing illegal immigrants and barbershops with unlicensed hair stylists.

In Prince George’s County, MD, alone, SWAT teams were deployed about once a day in 2009, overwhelmingly to serve search or arrest warrants, and half of those warrants were for “misdemeanors and nonserious felonies.” Much of Mr. Balko’s data is approximate, because police departments don’t publish data, and they uniformly oppose any attempts at transparency or oversight. But he has good Maryland data from 2009 on, because after the mayor of Berwyn Heights was mistakenly attacked and terrorized in his home by a SWAT team in 2008, the state passed a law requiring police to report quarterly on their use of SWAT teams: how many times, for what purposes and whether any shots were fired during the raids.

Besides documenting policy decisions at the federal and state levels, the author examines the influence of military contractors who have looked to expand into new markets. And he tells some pretty horrific stories of SWAT raids gone wrong. A lot of dogs get shot in the book. Most interesting are the changing attitudes of police. As the stories progress from the 1960s to the 2000s, we see police shift from being uncomfortable with military weapons and tactics—and deploying them only as the very last resort in the most extreme circumstances—to accepting and even embracing their routine use.

This development coincides with the rhetorical use of the word “war.” To the police, civilians are citizens to protect. To the military, we are a population to be subdued. Wars can temporarily override the Constitution. When the Justice Department walks into Congress with requests for money and new laws to fight a war, it is going to get a different response than if it came in with a story about fighting crime. Maybe the most chilling quotation in the book is from William French Smith, President Reagan’s first attorney general: “The Justice Department is not a domestic agency. It is the internal arm of national defense.” Today we see that attitude in the war on terror. Because it’s a war, we can arrest and imprison Americans indefinitely without charges. We can eavesdrop on the communications of all Americans without probable cause. We can assassinate American citizens without due process. We can have secret courts issuing secret rulings about secret laws. The militarization of the police is just one aspect of an increasing militarization of government.

Mr. Balko saves his prescriptions for reform until the last chapter. Two of his fixes, transparency and accountability, are good remedies for all governmental overreach. Specific to police departments, he also recommends halting mission creep, changing police culture and embracing community policing. These are far easier said than done. His final fix is ending the war on drugs, the source of much police violence. To this I would add ending the war on terror, another rhetorical war that costs us hundreds of billions of dollars, gives law enforcement powers directly prohibited by the Constitution and leaves us no safer.

Really Clever Bank Card Fraud

This is a really clever social engineering attack against a bank-card holder:

It all started, according to the police, on the Saturday night where one of this gang will have watched me take money from the cash point. That’s the details of my last transaction taken care of. Sinister enough, the thought of being spied on while you’re trying to enjoy yourself at a garage night at the Buffalo Bar, but not the worst of it.

The police then believe I was followed home, which is how they got my address.

As for the call: well, credit where it’s due, it’s pretty clever. If you call a landline it’s up to you to end the call. If the other person, the person who receives the call, puts down the receiver, it doesn’t hang up, meaning that when I attempted to hang up to go and find my bank card, the fraudster was still on the other end, waiting for me to pick up the phone and call “the bank”. As I did this, he played a dial tone down the line, and then a ring tone, making me think it was a normal call.

I thought this phone trick doesn’t work any more. It doesn’t work at my house—I just tried it. Maybe it still works in much of the UK.

Violence as a Source of Trust in Criminal Societies

This is interesting:

If I know that you have committed a violent act, and you know that I have committed a violent act, we each have information on each other that we might threaten to use if relations go sour (Schelling notes that one of the most valuable rights in business relations is the right to be sued—this is a functional equivalent).

Musing on Secret Languages

This is really interesting. It starts by talking about a “cant” dictionary of 16th-century thieves’ argot, and ends up talking about secret languages in general.

Incomprehension breeds fear. A secret language can be a threat: signifier has no need of signified in order to pack a punch. Hearing a conversation in a language we don’t speak, we wonder whether we’re being mocked. The klezmer-loshn spoken by Jewish musicians allowed them to talk about the families and wedding guests without being overheard. Germanía and Grypsera are prison languages designed to keep information from guards—the first in sixteenth-century Spain, the second in today’s Polish jails. The same logic shows how a secret language need not be the tongue of a minority or an oppressed group: given the right circumstances, even a national language can turn cryptolect. In 1680, as Moroccan troops besieged the short-lived British city of Tangier, Irish soldiers manning the walls resorted to speaking as Gaeilge, in Irish, for fear of being understood by English-born renegades in the Sultan’s armies. To this day, the Irish abroad use the same tactic in discussing what should go unheard, whether bargaining tactics or conversations about taxi-drivers’ haircuts. The same logic lay behind North African slave-masters’ insistence that their charges use the Lingua Franca (a pidgin based on Italian and Spanish and used by traders and slaves in the early modern Mediterranean) so that plots of escape or revolt would not go unheard. A Flemish captive, Emanuel d’Aranda, said that on one slave-galley alone, he heard “the Turkish, the Arabian, Lingua Franca, Spanish, French, Dutch, and English.” On his arrival at Algiers, his closest companion was an Icelander. In such a multilingual environment, the Lingua Franca didn’t just serve for giving orders, but as a means of restricting chatter and intrigue between slaves. If the key element of the secret language is that it obscures the understandings of outsiders, a national tongue can serve just as well as an argot.

Big Data Surveillance Results in Bad Policy

Evgeny Morozov makes a point about surveillance and big data: it just looks for useful correlations without worrying about causes, and leads people to implement “fixes” based simply on those correlations—rather than understanding and correcting the underlying causes.

As the media academic Mark Andrejevic points out in Infoglut, his new book on the political implications of information overload, there is an immense—but mostly invisible—cost to the embrace of Big Data by the intelligence community (and by just about everyone else in both the public and private sectors). That cost is the devaluation of individual and institutional comprehension, epitomized by our reluctance to investigate the causes of actions and jump straight to dealing with their consequences. But, argues Andrejevic, while Google can afford to be ignorant, public institutions cannot.

“If the imperative of data mining is to continue to gather more data about everything,” he writes, “its promise is to put this data to work, not necessarily to make sense of it. Indeed, the goal of both data mining and predictive analytics is to generate useful patterns that are far beyond the ability of the human mind to detect or even explain.” In other words, we don’t need to inquire why things are the way they are as long as we can affect them to be the way we want them to be. This is rather unfortunate. The abandonment of comprehension as a useful public policy goal would make serious political reforms impossible.

Forget terrorism for a moment. Take more mundane crime. Why does crime happen? Well, you might say that it’s because youths don’t have jobs. Or you might say that’s because the doors of our buildings are not fortified enough. Given some limited funds to spend, you can either create yet another national employment program or you can equip houses with even better cameras, sensors, and locks. What should you do?

If you’re a technocratic manager, the answer is easy: Embrace the cheapest option. But what if you are that rare breed, a responsible politician? Just because some crimes have now become harder doesn’t mean that the previously unemployed youths have finally found employment. Surveillance cameras might reduce crime—even though the evidence here is mixed—but no studies show that they result in greater happiness of everyone involved. The unemployed youths are still as stuck as they were before—only that now, perhaps, they displace anger onto one another. On this reading, fortifying our streets without inquiring into the root causes of crime is a self-defeating strategy, at least in the long run.

Big Data is very much like the surveillance camera in this analogy: Yes, it can help us avoid occasional jolts and disturbances and, perhaps, even stop the bad guys. But it can also blind us to the fact that the problem at hand requires a more radical approach. Big Data buys us time, but it also gives us a false illusion of mastery.

How Apple Continues to Make Security Invisible

Interesting article:

Apple is famously focused on design and human experience as their top guiding principles. When it comes to security, that focus created a conundrum. Security is all about placing obstacles in the way of attackers, but (despite the claims of security vendors) those same obstacles can get in the way of users, too.

[…]

For many years, Apple tended to choose good user experience at the expense of leaving users vulnerable to security risks. That strategy worked for a long time, in part because Apple’s comparatively low market share made its products less attractive targets. But as Apple products began to gain in popularity, many of us in the security business wondered how Apple would adjust its security strategies to its new position in the spotlight.

As it turns out, the company not only handled that change smoothly, it has embraced it. Despite a rocky start, Apple now applies its impressive design sensibilities to security, playing the game its own way and in the process changing our expectations for security and technology.
